How Can I Get the Month Name from a Numeric Month Value in MySQL?

Retrieving MONTHNAME() from Numerical Month Values

In MySQL, evaluating the month name directly from its numerical representation may seem like a simple task. However, the MONTHNAME() function is intended to convert actual date values, not numerical values.

Therefore, to obtain the month name for a numeric month (1-12), a workaround is necessary.

Solution Using STR_TO_DATE()

The STR_TO_DATE() function offers a solution to this challenge. It can transform a numeric month representation into a date format, which can then be used as the input for the MONTHNAME() function.

Syntax:

MONTHNAME(STR_TO_DATE(month_number, '%m'))

Example:

To convert the numeric months 6, 7, and 8 into their corresponding month names, use the following query:

SELECT MONTHNAME(STR_TO_DATE(6, '%m')), MONTHNAME(STR_TO_DATE(7, '%m')), MONTHNAME(STR_TO_DATE(8, '%m'));

Output:

+--------------------------------+--------------------------------+--------------------------------+
| MONTHNAME(STR_TO_DATE(6, '%m')) | MONTHNAME(STR_TO_DATE(7, '%m')) | MONTHNAME(STR_TO_DATE(8, '%m')) |
+--------------------------------+--------------------------------+--------------------------------+
| June                            | July                            | August                            |
+--------------------------------+--------------------------------+--------------------------------+

Caution:

While this approach provides the desired output, it's important to note that it can be slow when processing a large number of rows due to the overhead of converting each numerical month to a date and then back to the month name.
